This drink is made in Thailand using 'Hellbruboy' (a contraction of it's full name 'Hale's Blue Boy' Brand Syrup) a brand name sticky sweet red syrup drink that is added to hot water to make a hot drink. It can be bought in Thai supermarkets, look for the Thai name เฮลซ์บลูบอย. You can substitute strawberry milk shake syrup, it has a similar look but a different taste, sorry there really is no suitable substitute.
